摘要： A process for preparing carbonate compounds having the following formula:

wherein R and R' are, independently, a C₁ - C₆ alkyl group, a C₃-C₆ cycloalkyl group, an optionally substituted C₆-C₁₄ aryl group, an alkylaryl group, or an arylalkyl group is proposed; the process comprises preparing the carbonate compounds via a synthesis process comprising the step of
   (3) allowing the compounds represented by formula [IV] to [VII]:

   wherein R₅, R₆, R₇ and R₈ are, independently, hydrogen, a C₁-C₆ alkyl group, a C₁-C₆ alkoxyl group, a C₁-C₆ alkoxy carbonyl group, a substituted or unsubstituted phenyl group; provided that at least one of R₅ and R₆ is a substituted or unsubstituted phenyl group, and at least one of R₇ and R₈ is a substituted or unsubstituted phenyl group,
   to either each react with itself or to carry out replacement reaction between compounds [IV] and [V], [IV] and [V], [IV] and [VII], [V] and [V], [V] and [VII] or [V] and [VII] in the presence of a catalyst and a temperature from 100 to 300°C to obtain the compounds represented by formula [I].
